and State of Pennsylvania, have invented certain new and Saggars, fication. j

- This invention relates to new and useful improvements in apparatus for the burning of pottery or like articles,such as emery and more specifically my invention useful Improvements in of which the following is a specirelates to a new and improved type of saggar, each saggar being formed of a plurality of interengaged sections, and the sections being adapted to be'placed in superposed relation, with interlocking means carried thereby, thereby forming a very stable type of stand, which will not fracture or crumble under the intense heat to which devices of this character are'subjected. i j,

Another object of the-invention is to provide a new and improved type of saggar of this character which is formed with a centrally disposed aperture therein, that is adapted to support a removable fillingplug, said plug having a depending pin, that forms a supplemental support therefor, and also a centering means for the emery wheel,

orisimilar article that'isdisposed within the sagger during the burningoperation A still further object of theinvention is to provide a device of this character which is easily and simply constructedfinexpen be very efficient in operation.

' With these and numerous other objects in view'my invention consists of the novel features of construction, combinationand arrangement of parts which will be hereinpointed sive to manufacture, and one which will referred to and more particularly out in'the specification and claims.

' In the accompanying drawing:

Figure 1 is a top plan view of my new and improved saggar; a Fig. 2 is a side elevation of the same;

Fig.3 is a vertical'section taken on the lineS-B of Fig. 1; j l I Fig. 4 is a top plan view modified type of sa'ggar'; l

Fig. 5 is a section taken on the line 5-5 of Fig. 4t; and

of the slightly Fig. 6 is a further modified form of'a saggar. I

ltn describing ray-invention I shallrefer stood in which is edges of each section, to register with correspondingly shaped I rounded recesses 6 on the adjacent edges of to the drawings in which similar reference characters designate corresponding parts throughout the several views. My new and improved saggar, which is designated in its enti'rety'by the plurality ofsections, preferably 1 to 4-in number, each section being formed'with,

owingto the fact that the saggar is cylindrical, a cylindricalwall portion 2, and "a top sector portion 3. 1'1 he saggar 1 is formed with an open bottom, asit will be underpositioned the pottery, such as an emery wheel, or the like, and the same is embedded in tioned. These saggars are adapted to be placed in superposed relation, formingwhat is termed a stand, when they are subjected to the burning operation. Each of the sections is provided with a projecting hand holdportion 4, on the outer surface of the cylindrical portion 2, said portions tbeing disposed in alinement, and adapted to form an annulanring, whereby the various sections of the saggars to hold articlesfmay be easily placed in position. e

To securely hold the various sections of the saggar in interlocked relation, when the same are in position, I have provided a plurality of rounded projections 5 on one of the which are' adapted contiguous sections, These projections and recesses extend from the bottom of the saggar sections. This interlocking engagement is clearly shown in Fig. "2 of the drawings, and the same when in operation will securely hold the various sections together to form a very stable article, that will not be likely to slip during the burningoperation. In addition to'these interlocking means provided for the various sections, the-top of the saggar sections is provided onone edge with projecting ribs Ythereon, and on the .otheredge a correspondingly shaped annular groove 8, whereby when the sections are placed in position, these ribs and grooves are adapted to register, hence to securely hold said saggars in this positiorn r The sector portions 3 of the top of the saggars are formedwith concaved corners adjacent the point of intersection of the division lines of the structure in' the topwall thereof, which are designated by the numeral 9, and which when the saggar secnumeral 1 is formed of a sand when so positions' are assembled is adapted to form a centrally disposed aperture therethrough. These apertures are formed with stepped shoulders 10 onthe'inner edge thereof, and adapted to be positioned for each saggar, which is formed with stepped correspondingly shaped shoulders 12 on the marginal edge thereof adapted to engage the shoulders 9 of the apertures.

The plugs 11 are primarily supported in the apertures in the tops of the saggars as has been hereinbefore described, and to provide asupplemental supporting means therefor, to prevent-said plugs from slipping should the various sections work apart slightly, I provide a supplemental supporting means 1 1, which comprises a pin having its upper end embedded in the lower surface of the plug, and said pin extending downwardly to a point on the plane of the lower edge of the cylindrical wall portions 2 of the sections of the .saggar. I Thus it will be obvious'that when the saggars are disposed in superposed relation, the bottom of the pin 14 will rest on the top of the plug 11 in the saggar directly beneath the same, to support saidfirst mentioned plug securely in position. This pin forms also a centering means for the structure when the same is used for burning an .emery wheel, as the pin is positioned through the aperture in said emery wheel.- In Figs. 4 and 5 of the drawings I have illustrated a slightly modified form of saggar, that is formed in four sections, and which is provided with a slightly modified type of holding means for the plug 11. The plug 11 in this form of the type, and the adjacent portions of the sections are provided with beveled shoulders 15, which are adapted by interlocking engagement to support-the plugs when the sections are assembled, as clearly shown in Fig. 5 of the drawings. This. plug is provided with the usual type of pin 1 1 depending therefrom. as used in the other type of the device. This type for supporting the plugs need not necessarily beemployed only on the four section saggar, as the same is equally applicable to the saggar formed of three or a greater number of sections, it being only necessary that the shoulders of said sections being beveled so as to cooperatively engage the shoulder on said plug. The various other interlocking features of the saggar are similar no matterhow many sections are emp yed In Fig. 6 of the drawings I have shown a comparatively simple type of saggar that is adapted to be employed for making small emery wheels, and which includes a cylindrical body portion 16. provided with an annular handholdring 17 projecting laterally .fromits upper *edge, and :said ring forms. an.additional:.;supnort, soathat; these saggars are adapted to be superposed to form a stand. This type of saggar does not employ the type of plugs used in the other saggar, and is only used where the wheels are comparatively small. A. plurality of emery wheels are positioned within the cylindrical body portion, the same being embedded in sand, as clearly illustrated in Fig. 6 of the drawings.

In operation these saggars are adapted to be placed in superposed relation, to form a stand, which is subjected to intense heat to burn the article of pottery contained therein. In the formation of this stand, after one sagg'ar is placed in position. a certain amount of sand is poured on the top of the same, and then the other saggar is assembled and placed around the same, with the plug removed, whereupon s'utlicient sand is poured through the aperture to entirely em.- bed the emery wheel, or other article of pottery contained therein, and then the plug 11 is placed in position in the aperture, the pin 14 extending throughsaid saggar and resting on the top of the plug of the saggar directly beneath the same. This operation is repeated until the stand reaches the desired height.

Although the saggars are formed in sections, the interlocking means on the adjacent edges thereof will securely hold the various sections together and form a very stable article of this character. The saggars are also provided with additional interlocking means to hold them securely in superposed relation, and prevent them sagging or slipping under the intense heat to which they are subjected. The pin 1 1- in addition to being a centering means for the emery wheel or article of pottery contained in the saggar, also forms av supplemental support for the plug 11 and prevents said plug from slipping through the aperture should the vari ous sections spread slightly. The said shoulder arrangement that primarily supports the plug in position prevents sand from leaking therethrough and forms a very safe and secure means for ordinarily holding said plugs stationary.

It will be understood that the various sections of. this saggar are formed of fire clay, and broken portions of old saggars, that are molded in the herein-described shape, and so formed.

From the foregoing description, taken in connection with the accompanying drawings. the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation vof the invention, together with the device which I now considerto behest embodiment thereof, I desire to have it understood that the de vice :shown .is merely. illustrative, and a that certain changes may be made when desired as are Within the pended hereto.

Having fully describedmy invention What I claim as new, and desire to secure by Letters Patent, is:

1. A saggar of the class described including a sectional body having a centrally disposed aperture in the top thereof,.a plug removably filling said aperture and supported therein, and supplemental supporting and centering means depending from said plug.

2. A saggar of the class described including a sectional body having a centrally disposed aperture in the top thereof, a plug reinovably filling said aperture and supported therein, a plurality of correspondingly scope of the claims ap- Copies of this patent may be obtained for five cents each, by addressing the stepped shoulders on the inner surface of sad aperture and the plug to support said plug, and supplemental supporting and centering means depending from said plug.

A saggar of the class described including a sectional body having a centrally disposed aperture in the top thereof, a plug removably filling said aperture, a plurality of correspondingly stepped shoulders on the inner surface of said aperture and the plug to support said plug, and a pin depending from said plug and extending through the body to a point in the plane of the lower edge thereof.

In testimony whereof, I affix my signature hereto.
